To all whomz may concern! Be it known thatI, WiLLIAM A. JAMES, a citizenof the AUnited States,` residing fat Bishopville, in thecounty of LeeandState of South Carolina, have invented certain new and usefulImprovements in Couplings; and I do hereby declare the following to be afull, clear, and exact description of the invention5 such as will enableothers skilled in the art to which it appertains to make and use thesame.

T his invention relates to a coupling truck structure which is designedfor attachment to tractors whereby the ordinary type of single or doubleshovel one horse cultivator may be attached to a tractor, in multiplerelation, for the proper cultivation of various types of crops such ascorn, cotton or the like.

An object of this invention is to provide a coupling structure asspecified which is comparatively simple in construction, durable andwhich is designed so that a plurality of implements may be hitched to atractor so as to eliminate the necessity of the employment of horses forpulling the cultivator or implement.

1With the foregoing and other objects in view this invention consists insuch novel features of construction, combination and arrangement ofparts as will be hereinafter more fully described, illustrated in theaccompanying drawing and claimed.

ln describing the invention in detail reference will be had to theaccompanying drawing wherein like characters designate like andcorresponding` parts throughout the several views, and in which:

Figure 1 is a rear elevation of the improved coupling truck,

Fig. 2 is a top plan view of the coupling, and

Fig. 3 is a section on the line 3--3 of Fig. 2. i

Referring more particularly to the drawing, l indicates the mainsupporting bar of the coupling truck structure which has a pair ofupstanding bearings 2 formed upon its end. The bearings 2 rotatablysupport vertical shafts 3 of forked members 4, which forked memberscarry axles 5 at their lower ends upon which supporting wheels 6 aremounted. The shafts 3 are rotatably mount ed within the bearings 2 so asto provide a swiveledf mounting for the wheels 6.

A bar 7 which has its ends bent obliquely to the line of travel of thecoupling is attached to the bar 1 so that the greater porsupportingrtion 8 of the bar will be parallel to the bar l and in spaced relationthereon. Suitable braces 9 are provided which are attached to the bars 7and l, as clearly shown in F ig. 2 of the drawing for bracing thecoupling structure and also for forming a brace for the main couplingrod 10 which has an eye 11 formed upon its forward end to which thecoupling of a tractor is hitched or conuected. A pair of bolts 12 areprovided which extend through the portion 8 of the bar 7 near its ends,through the angled ends of the braces 9 and through Vthe bar 1. rihebolts 12 also attach plates 13 to the forward outer surfaces of theportion 8 of the bar 7 at its ends. The plates 13 have their inner endsangled as shown at 11i, and they have rings 15 connected thereto.

Stay chains 17 are attached to the rings 15 and are provided forattachment to the tractor which is coupled to the rod l() and they aredesigned for more securely con necting the coupling member to thetractor. The bolts 12, the bracing bolts 18, and the bolts 19 whichsecure the ends of the bar 7 to the bar 1 are all provided with eyes 20which extend upon the opposite side of the bar 1 from the bar 7 asclearly shown in Fig. 2 of the drawing. Chains or analogous flexiblemembers 21 are connected to the eyes 20, and these chains or flexiblemembers are adapted for connection with the elevises carried by theforward ends of the beams of the usual type of single shovel cultivatoremployed in the southern sections of the country. However, it is to beunderstood that the ordinary type of multiple shovel cultivator may beattached to the coupling structure if desired without departing from thespirit of this invention.

The bar 1 has a plurality of eye bolts 22 attached thereto intermediateeach pair of' the eyes 20 and these eye bolts are adapted for havingflexible members connected thereto if it is so desired, they beingprovided for permitting of the proper spacing of the implements whichare connected to titi the coupling st rnctnre.
